Vision evolution

Apparently, photopic vision relates to "sunlight", to which the humcui had adapted through evolution, while scotopic vision related to "moonlight", that is, sunlight modified by reflection finm the Moon s surface. However, it was soon discovered that the color responses of individuals were not exactly the same. Each individual "sees" a color slightly differently from anyone else. We have learned to discriminate between colors but no one knows exactly what anyone else actually sees. 

The vision of irreversibility that appeared in this first group of works, which formed the object of the first monograph on nonequilibrium statistical mechanics by Prigogine (1962, LS.9), was the following. The necessary conditions for an irreversible evolution were ... 

The chemical diversity of the world as reflected in Mendeleyev s periodic table and the elemental abundance table finally has its explanation. Today we have reached the stage where we can study the chemical evolution of the galaxies with a view to writing the story of each element in its own astrophysical context. Let us not forget the name of Beatrice Tinsley, who initiated this vision, but died too soon to witness its achievement.

Now that the black box of vision has been opened, it is no longer enough for an evolutionary explanation of that power to consider only the anatomical structures of whole eyes, as Darwin did in the nineteenth century (and as popularizers of evolution continue to do today). Each of the anatomical steps and structures that Darwin thought were so simple actually involves staggeringly complicated biochemical processes that cannot be papered over with rhetoric. Darwin s metaphorical hops from butte to butte are now revealed in many cases to be huge leaps between carefully tailored machines—distances that would require a helicopter to cross in one trip.

The eye scrutinizes me and holds me in thrall. He iS slightly threatening and feels like a sea mammal, but not a regressive vision to an earlier stage of evolution. On the contrary, he seems to be from the future, or at least he seems more evolved than the human race. I fear being in the presence of something much more powerful and more evolved than I a god ...
